The Lowdown

G’day, it’s Rusty here. Let’s cut to the chase. The next couple of weeks at Jaconé are a bit of a mixed bag, but there are a couple of proper windows where it’s gonna turn on. For the most part, we’re looking at smaller, cleaner surf with the odd pulse of energy, and then a couple of bigger days that are strictly for the experienced crew. The water temp is sitting at 72.3°F, which is a touch warmer than average for this time of year, nothing dramatic, but you’ll notice it.

Right now, we’ve got a bit of a slow patch to kick things off. Friday morning the 28th has some clean 4.3ft south swell, but it’s a bit weak, with combined energy only reading 651. It’s rideable, but not gonna get the heart pumping. The wind is offshore though, so the surface will be nice and clean. The afternoon drops off a touch.

Saturday and Sunday are pretty quiet. Saturday morning has some 3.9ft east swell, but the period is a short 7 seconds, so it’s gonna be a bit lumpy and disorganised. There’s still some clean conditions early with a light offshore breeze, but don’t expect much push. Sunday morning is glassy with a tiny 3.3ft east swell, but again, it’s just very ordinary. These are days for the log if you’re desperate, not for a proper session.

Monday the 31st picks up a little. The morning is small, but the afternoon builds to a fun 4.3ft east-northeast swell with a little more period (8 seconds) and a clean offshore wind. That’s the best of the next few days, but nothing to write home about.

Then things go a bit flat again on the 1st of September, with some poor onshore winds and weak waves. Not worth getting wet for, to be honest.

Now, here’s where it gets interesting. The 2nd of September brings a serious jump in size, but it’s a warning, not a celebration. We’re looking at a 9.8ft to 11.5ft south-southwest swell with a long 13-15 second period. That’s a big, powerful groundswell, and the combined energy is massive, reading 4691 on Wednesday morning. But plain and simple, this is way too big for Jaconé. It’s an exposed break, and this much energy is going to be a washing machine. Only for the most experienced chargers, and even then, it’s likely to be a close-out. The wind is onshore too, which will chop it up further.

Early Thursday morning the 3rd is the first real standout. The swell has dropped to a still-chunky 7.9ft from the south-southwest, with a solid 11-second period. The wind is glassy, just a slight air. This is going to be firing. The energy is still strong (1403), and for the experienced surfer, this is the pick of the first week. It’s pushing the limits, so leave the beginners on the beach. The afternoon stays fun for experts, with 6.9ft south swell and a light cross-shore breeze.

Friday the 4th is another good one. The swell is a more manageable 5.9ft from the south, with a clean offshore ENE wind. Combined energy is moderate at 751, but the conditions are going to be pristine. This is a great day for a wide range of surfers, with clean, well-shaped waves. The morning is the go; the afternoon wind picks up and swings more east.

The weekend of the 5th and 6th fades out again. Small, weak swell, not much energy. Sunday the 6th has some stormy weather with light rain, but there’s a bit of a long-period south swell (15-16 seconds) filtering in, but it’s only 1.6ft. Not enough to do anything with.

Then, the second week kicks off with another solid pulse. Monday the 7th of September is looking like a classic. You’ve got a 5.9ft south swell with a 13-second period, and it’s glassy again in the morning. The energy is strong (1076) and the conditions are clean. This is another standout for the experienced crew, with great shape and power. The afternoon builds to 7.2ft but gets a bit cross-choppy.

Tuesday the 8th sees another big bump in size, with 8.2ft south-southwest swell, but the wind is onshore and howling at 12-16 mph. It’s going to be a stormy mess, and the “poor” conditions will make it a battle. Not worth the paddle.

The rest of that week settles down into a more average pattern. We’ve got a few days of 4.3ft to 6.2ft south swells, but the winds are often cross-onshore or just messy, with some periods of light rain. It will be surfable, but nothing special. There’s a

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
